REPORT ON ENVIRONMENTAL IMPACTSOF FOREST PRACTICES -

A 225 page report by DR. W. (Bill)FREEDMAN of Daihousie Institute forResource and Environmental Studies,has recently been published and Isavailable from the office of IRESDalhousie University, 1312 RobieStreet, Halifax, B3H 3E2 (424—3632).

The report provides an overviewof the environmental impacts associated with ongoing and foreseeableforestry practices in the Atlanticprovinces. It contains a literaturereview and an interpretation of thetransitory and long—term effects ofpesticide use, harvesting, roadconstruction, site preparation andplantation establishment on wildlife and its habitat, aquatic life,water quality, soil characteristics,and forest species composition.

Many butterflies spend the winteras pupae, with much of their bodyfluid converted to a chemical closelyrelated to anti-freeze, which allowsthem to endure sub—zero temperatureswithout freezing. As winter comes toan end, the warmer temperatures trigger the final stages in the transitionfrom a larva to an adult.

Among the earliest of these toemerge are the Elfins (Incisajia sp.).Well-named: they are small, about thesize of a penny, inconspicuously cladin drab brown, and look like shadowsas they dart from place to place.They may be found on blueberry barrensand near pine or spruce forest fromthe middle of May into early June.

We have two species inNova Scotia: the Dreamy Dusky Wing(Erynnis icelus ) and Juvenal ‘ s DuskyWing (E. juvenaZi~. Both are basically brown, with a sprinkling ofsmall tan—coloured spots on the hind—wings. Juvenal’s is the larger, andcan be identified by the presence ofsemi—transparent (hyaline) whitespots on the fore-wing. Both speciesseem to adopt favourite localitiesin the sun, from which they makebrief forays to drive off otherbutterflies, investigate flowers,orwhat—have-you, before returning onceagain to rest in the warmth of theirfavourite spot.

By the first week of June, thebutterfly population is really starting to grow, and we begin to see the‘summer’ species. Watch out for theappearance of our big yellow swallowtail, the Northern Tiger Swallowtail(Papilio glaucus canadensis). Theseare abundant along the Waverley roadbetween the Micmac Rotary and Oakfield.

6THE PIPING PLOVER PROBLEM IN NOVA SCOTIA

Concern is growing over the condition of many Nova Scotia publicbeaches where disturbance anddestruction by motorised vehicles areon the increase. Several letters onbehalf of HFN have been sent to theMinister of Lands and Forests, Hon.George Henley, requesting that theBeach Protection Act be enforced atall public beaches before irreparabledamage is done.

Of particular urgency is the caseof St.Catherine’s River Beach inQueens County (originally Cadden Bay).Granted - damage there is not yetsevere; the immediate problem Is thewelfare of the Piping Plover whichnests there on the bare sandy habitatjust above high water mark, where

ened in Canada, actually it now maywell be on the endangered list.

Based on studies done in 1976—77towards an MSc by Winifred Cairns, sheand Ian Melaren published a paper in“American Birds” in 1980 estimatingthat at most 910 pairs were nestingalong the whole Atlantic Coast ofNorth America from Virginia to Newfoundland. Of that total a maximumof 70 pairs were estimated for all ofNova Scotia — most of the nestingsites being along the south coast inShelburne, Queens, Lunenburg andHalifax Counties. Between 27—29pairs were estimated as nesting onSt. Catherine’s River Beach in 1976 —

at that time a quiet, relativelyisolated privately owned property.

Last year Stephen Flemming andRoland Chaisson of Acadia Universityreleased their preliminary report onthe Piping Plover and the need to reduce human disturbance. They gaveonly 15 pairs as nesting at St.Cath—erine’s Bay Beach in 1982 — areduction of nearly 50% since the

Nova Scotia government expropriatedthe Woods property and it became apublic beach. Flemming and Chiassonare already on the beach this yearcontinuing their study and hoping bytheir very presence to be able toeffect some safeguard for the birdsduring the critical weeks of May andJune, by deflecting ‘traffic’ awayfrom the nesting area.

Late last year the Province ofNova Scotia appointed a Committee toexamine alternate uses of the property. Public hearings were held andthe Committee made well aware of thePiping Plover problem. The Committeesubmitted its Report to Governmentin March 1983, but at the time ofwriting neither Report nor recomn’endations have been released to thepublic. HFN and Canadian NatureFederation have both written to theProvincial Government pointing outthe urgency of the situation andrequesting that immediate steps betaken to protect the site — at leasttemporarily — during this currentnesting season. Perhaps you wouldadd your voice by writing your ownletter to The Honourable GeorgeHenley, Minister of Lands and Forests,Government of Nova Scotia, P.O.Box698, Halifax, B3J 2T9.

MEANDER RIVER FIELD TRIPS

When acting as leader on severalHFN trips to the Meander River Inter—vale, I have been asked questionsabout the history of the area. Newporas the district is known,has a longrecord of settlement, and containsmany well—established farms. RecentlyI came across a book called Men ofthe Soil, published by the NovaScotian Beautification Committee,which gives brief histories of theCentury Farms of the province. Togive some background information forthe benefit of members who accompanied me on these field trips Iquote extracts from the sectionsdealing with the Harvey family, whoseproperty we are privileged to visit.

A land grant bounded by the Meanderand Herbert Rivers was given to hiseldest son, James; in the log cabinbuilt there in sight of the MeanderRiver his family was born — 13 sonsand 5 daughters.. .each son was givenapproximately 200 acres of theirfather’s grant of land... The landnow known as GRAND ELM FARM going toBenjamin, who cleared land and put up

a log cabin.. .later building a framehouse and a barn. About 1836 his twoeldest sons each planted a tree - onean apple, the other an elm. Theapple tree bore fruit until 1954 whenit was uprooted by hurricane “Edna”.The huge elm still stands and is theone from which the farm gets it name.

Later, John Murdoch and his sonsincreased their cultivated acreageby clearing land originally clearedin 1822... purchased neighbouringfarms bordering the Meander andincreased the farm area to the present 450 acres... raising of beef andhogs are chief operations on theHarvey farm today.

Five generations of Harveys haveoccupied this farm...which has gonethrough many stages,from beingpractically self—sustaining in pioneer days, through mixed farming tothe present day dairy farm supplyingmilk to the Halifax market.

Some knowledge of the humanhistory complements the naturalhistory of such a beautiful andscenic part of our country. It alsohelps me in answering the manyquestions fired at me during thecourse of our walks.

The book treats 36 species or spe~cies groups beginning with wild riceand including many berries (blue—,black—, elder—, rasp—, cran—, etc)and nuts (acorn—, hazelnuts etc.) aswell as plums, cherries and wildgrapes. Unfortunately almost half ofthe species discussed are not nativeto Nova Scotia.

All the fruits are treated simil,arly. Each has sections labelled“Other Names” (if any); “SuggestedRecipes”; “How to Recognise”; “Whereto Find”; “How to Use”; “Warning” (ifany); and “More for Your Interest”.The botanical name for each group isat the bottom of the first page. Eachspecies has a line drawing or colourphoto showing leaves and fruit.

The “Warnings” treat the readeras an intelligent being. For example(p.162): (the seeds of apples andpears) “contain a cyanogenic glyco—side that has an almond—like flavourand releases hydrocyanic acid. Smallamounts for flavour are not dangerous,but toxic reactions may result fromlarge amounts.., bark and leaves ofapple and pear trees should not beconsumed”.

Recipes include jellies, jams,raspberry bread, rose—hipcherry pudding, lamb shanks

The same man (Pierre they calledhim) was obviously the leader andteacher. As they walked he talkedof the trees and the coming of Springand members of the flock broughtstems and buds to him.

He wanted proof of what I reportedbefore conceding defeat In the contest for the first sign of Spring.We returned to the Frog Pond butthe flock of naturalists were nowhere to be seen. Bill said I wascrazy and refused to recognise myreport as being the first sign ofSpring. But why should I carewhat he thinks..., next year I won’tbe looking for the first sign ofSpring - I’ll be accompanying theHFH’ers to commune with Spring uponher arrival.

PS. — Found this list on a loosepiece of paper caught amongst a clumpof Japanese Knotweed — may be aguide to someone looking for Springat Frog Pond In the future.
